摘要
To investigate the radiation characteristics of reflector antennas with surface deformation and perforation, the physical optics (PO) method and physical theory of diffraction (PTD) technique are used to calculate the far field and the diffraction of the reflector edge. The computational method is verified reliably by comparing the calculation curve with the experimental curve. As a consequence, the radiation patterns for different deformation properties and different perforation densities are computed. The results show that the deformation of the reflector surface greatly affects the radiation pattern. But in the calculated density range of holes, perforation affects the radiation characteristics less.
